Re im z
TīmeklisThe two functions Re (z) and Im (z) are in fact linear: (2) Re (tz + sw) = tRe (z) + sRe (w), Im (tz + sw) = tIm (z) + sIm (w), for any real t and s. In particular, Re (z - w) = Re (z) - Re (w), Im (z - w) = Im (z) - Im (w). It follows from (2) that the z' is also linear, i.e., for any real t and s, we have (tz + sw)' = tz' + sw'. http://pirate.shu.edu/~wachsmut/complex/numbers/plane.html

In this sense, there is no formula for ℜ ( z) that does not involve z ¯, because the Cauchy–Riemann equations fail for ℜ ( z) : ∂ ℜ ( z) ∂ z ¯ = 1 2 ≠ 0 Share Cite …
TīmeklisThen jzj = Re(z) + i(Im(z) + 1). Hence, since jzj 2 R, necessarily Im(z) = ¡1. The equation then is p (Re(z))2 +1 = Re(z), and, squaring, we obtain 1 = 0. 9. We will use the notation z = a+ib, a;b 2 R. a) The equation becomes a¡ib = i(a+ib¡1), that is a¡ib = ¡b+i(a¡1). Then a = ¡b and ¡b = a¡1, which has no solution; We conclude that ...

TīmeklisSimilarly Re(z−w) = Re(z) −Re(w). (ii) Note that Im(z+w) = Im(a+ib+c+id) = Im((a+c)+i(b+d)) = b+d= Im(z)+Im(w). Similarly Im(z−w) = Im(z) −Im(w). Almost any two complex numbers picked at random will give an example for which Re(zw) 6= Re( z)Re(w). For example, choose z= i, w= −i. Then zw= 1. However,
TīmeklisThe functions Re, Im, Mod, Arg and Conj have their usual interpretation as returning the real part, imaginary part, modulus, argument and complex conjugate for complex values. The modulus and argument are also called the polar coordinates.
